BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The invention relates to an in-skate having a pliable boot and abase frame, and more particularly, to an in-line skate having a pliableboot and a base frame, in which flanges disposed with correspondingthrough holes and lugs are provided for fitting the tracking system andthe shoe body thereof into a lower protection base thereof so as to forma flexible body capable of dispersing the stress produced by bouncing orturning at high speeds.

[0003] (b) Description of the Prior Art

[0004]FIG. 1 shows a conventional elevational view of a prior art.Because of the flourishing of in-line skates during the recent years,various brands of in-line skates have become available successively.However, there are no significant differences apart from the stylesthereof with respect to the prior in-line skates. Referring to FIG. 1,the structure of a conventional in-line skate comprises a shoe body 1consisted of a boot 12 fitted into an attachment frame 17, a trackingsystem 15 attached to the bottom of the attachment frame 17 by means oftwo attachment members 18 using rivets 16, and a plurality of wheels 153pivotally disposed at the bottom of the tracking system 15 for slidingmovements. Nevertheless, the design of such prior art has not taken inthe consideration that the third wheel (A) and the fourth wheel (B)thereof bear the largest stress from withstanding most of the bodyweight. As a result, during turning or braking at a high speed or evensudden landing after jumping, the attachment members 18 connecting theattachment frame 17 and the tracking system 15 often break on the spot(as indicated by symbol C in FIG. 1), further causing damages andirreversible body injuries. Such shortcomings have long since botheredand perplexed industrialists as well as consumers. Therefore, it is avital task to provide an in-skate having a pliable boot and a base framehaving enhanced practical values.

SUMMARY OF THE INVENTION

[0005] Therefore, an object of the invention is to provide an in-lineskate whose tracking system and attachment frame are free from breakagecaused stress produced during turning or braking at a high speed orsudden landing by dispersing the produced stress thereof to the variousmembers of the invention, thereby obtaining an-line skate having moredurable members as well as better safety.

[0006] In order to accomplish the aforesaid object of the invention, thestructure in accordance with the invention comprises a lower seat havinga flange provided at the bottom of a shoe body, a base frame providedbelow the lower seat for fitting the shoe body and having lugs formed bydownwardly extending the front through holes with corresponding throughholes for the flanges to penetrate through, a lower protective seatprovided at the two sides of the rear through holes of the base framefor fitting the shoe body and attaching to a protective boot above. Theaforesaid members are then combined into a flexible body using rivets sothat stress produced is immediately dispersed, thus avoiding breakage ofthe members thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The structure in accordance to the invention shall be describedwith the accompanying drawings hereunder.

[0013] Referring to FIGS. 2, 3 and 4 showing an elevational view, anexploded elevational view and a side view according to the invention,respectively, the invention comprises a shoe body, a base frame, atracking system, a lower protection seat and a protective boot. Wherein,below the shoe body 12 is provided with a lower seat 121 furtherprovided with U-shaped flanges 122 that are wider at the top andnarrower at the bottom at both the front and rear sides thereof forrivets 16 to penetrate through, and at the flanges 122 provided at thefront and rear sides are disposed with through holes 121. The twoU-shaped flanges 122 above serve as illustrative purposes of theembodiment according to the invention, and the number of the flanges 122is not limited but may be two or more. At the bottom of the lower seat121 is provided with a base frame 13 for fitting the shoe body 12 and atracking system 15. The base frame 13 is provided with through holes 132at corresponding positions thereof for penetrating through the flanges122 of the aforesaid lower seat 121. The front through holes 132extended downward are further disposed with lugs 131 having throughholes 1311. Referring to section B in FIG. 3 showing a partial enlargedview, the base frame 13 is for fitting the tracking system 15, and atracking frame 151 is provided with wheels 153 for sliding movements. Inorder to fasten the lugs 131 at the sides to the tracking system 15 byinserting through the through holes 132 at the front of the base frame13, and to fasten the flanges 122 at the rear of the lower seat 121 ofthe shoe body 12 and a protection seat 14 below the shoe body 12, atpositions of the tracking frame 151 of the tracking system 15corresponding to the lugs 131 are provided with rivets 16 and throughholes 152 for inserting screws.

[0014]FIGS. 4 and 5 show a side view in accordance with the inventionand a sectional view of FIG. 4 along 5-5, respectively. During theassembly thereof, the base frame 13 is fitted into the lower seat 121 ofthe shoe body 12. For that the base frame 13 is provided with throughholes 132 at the front and rear thereof, respectively, and the throughholes 132 at the sides of the base frame 13 then enable the flanges 122of the lower seat 121 to extend downward. In addition, also because therear of the base frame 13 resembles the design of an inverted hood, theheel of the shoe body 12 is accommodated therein. In the meantime, thelugs 131 extended at the sides of the front through holes 132 enclosethe outer edge of the tracking frame 151 of the tracking system 15, andtherefore the front flanges 122 are fitted into the interior of thetracking frame 151 provided with through holes 152 of the trackingsystem 15, and further form a flexible body by inserting and fasteningwith rivets 16 or screws. Moreover, the flanges 122 at the lower seat121 protruing through the rear through holes 132 of the base frame 13are fitted into the through holes 152 of the tracking frame 151. Inorder to have the lower protection seat 14 provided with through holes141 enclose the outer edge of the tracking frame 151 simultaneously,openings 142 are disposed at the center of the lower protection seat 14,so as to further directly fasten the flanges 122 at the rear of thelower seat 121 to the rear through holes 152 of the tracking frame 151of the tracking system 15 via the base frame 13 and the lower protectionseat 14, thus forming a flexible body. In addition, the upper portion ofthe invention is provided with a protective boot 11 for protectionpurposes. It is illustrated from the above that, in accordance with theinvention, the shoe body 12 is fastened to the lower seat 121, and thelower seat 121 is further combined with the base frame 13 through theflanges 122 and the front lugs 131, and the tracking system 15 throughthe front through holes 152. Not only the heel of shoe body 12 isenclosed by the rear base frame 13, the lower protection seat 14 is alsofastened to the tracking frame 151 using the flanges 122 through theopenings 142 and the rear through holes 152. The through holes 152 atthe sides of the tracking system 15 are enclosed at the lower sides ofthe lower protection seat 14, so as to form two flexible bodies usingrivets 16 or screws. As a result, stress produced from progressing,turning or braking at high speeds, or even sudden landing, iseffectively dispersed to the various members of the invention, therebypreventing breakage causing dangers and accidents as well as lengtheningthe lifespan of the members.
